"I think Joshua is a beautiful name. And one night I sort of approached him [husband Joshua Kelley] with it and said: 'What do you think about a junior?'"

"He, in the past, said that he hated that idea and he could never be that guy, but I couldn’t - I wasn’t finding something [a name] that I was responding to."

Katherine continued: "And he was like, 'Aw, I love that. That would mean a lot to me'."

Meanwhile, the Grey's Anatomy star also spoke about her decision to adopt her daughters Naleigh, eight, and Adalaide, five, to Entertainment Tonight.

"I knew for certain that I wanted to adopt from Korea," Heigl said of adopting her oldest child, Naleigh."

"My sister's Korean and she's my big sister and hugely important to me and my best friend. I just knew I wanted my family to sort of look like the one I came from. So I always knew I was going to do that,' she added.

As for Adalaide, the star added, "I never thought I would adopt domestically, but that just sort of gracefully happened and it did feel like grace."
